The right sander for a project will vary on a case-by-case basis, but a dual action sander (DA sander)<\/a> tends to do an excellent job when you have to sand\u00a0and<\/em>\u00a0buff at the same time. So what is a DA sander, and how is it used?<\/p>\n\n\n\n

A dual action sander is a tool that combines the best functions of disk and belt sanders<\/a>. DA sanders are powerful and versatile and are used for sanding and buffing. Dual Action sander moves backward and forward, copying the linear action of a belt sander, but are also slightly rotary.<\/strong><\/p>\n\n\n\n

Many woodworkers rely on a DA sander a great deal. The rest of this article will go into a bit more detail, highlighting everything you need to know about this tool and why you should have it in your shed.<\/p>\n\n\n\n

What Is a DA Sander?<\/h2>\n\n\n\n

To understand a dual action sander, you have to first look at the two sanders it is loosely based on, which are the\u00a0belt sander<\/a> and the disk sander<\/strong>.<\/p>\n\n\n\n

Belt sanders are designed to run a sandpaper belt at high speeds, scraping away lots of material quickly. They are useful when you\u2019re removing high bumps on flat surfaces. However, they are often too powerful, removing too much material or leaving scratches if you don\u2019t work gently.<\/p>\n\n\n\n

The disk sander design is such that it spins a disk of sandpaper in a circle at high speeds, which allows it to sand uneven materials using the edge of the disk.<\/p>\n\n\n\n

Some disk sanders have a typical wobble in their movement, ensuring the sander doesn\u2019t dig too much into the surface you\u2019re sanding. However, this doesn\u2019t prevent scratches across the grain while working on wood.<\/p>\n\n\n\n

Now,\u00a0dual action sanders combine the best of both sanders we\u2019ve seen above<\/strong>. The sandpaper pad on these also moves in the linear backward and straightforward movement of the belt sander, but there\u2019s also the slightly wobbly or circular motion of the disk sander. The movement is rotary most of the time, but it can also look randomly orbital.<\/p>\n\n\n\n

The dual-action mechanism on a DA sander may vary from one product to another.<\/p>\n\n\n\n

In some, the sandpaper may appear circular and spin like the disk sander. In others, it can be rectangular, moving in a semi-rotary motion where the paper doesn\u2019t turn while working.<\/p>\n\n\n\n

How Does a DA Sander Work?<\/h3>\n\n\n\n

A DA sander<\/a> comes with two modes:<\/p>\n\n\n\n

The first mode locks the sanding pad into spinning in a flat-plane circle.<\/p>\n\n\n\n

Turning on the second mode will move the pad using an internal bearing.<\/p>\n\n\n\n

This delivers the wobbly movement, which allows it to work without creating excess friction against the surface.<\/p>\n\n\n\n

The dual-action nature of a DA sander gives you more options for completing your sanding projects. You can use the locked rotation function when you need to clear some materials fast. The wobbly or orbital motion works well for creating a smooth finish.<\/p>\n\n\n\n

The polishing action or sanding disc on a DA sander is connected to a motor system that spins via a gear system.<\/p>\n\n\n\n

The motor is responsible for the movement, you see. The sander design allows it to cover large areas of any surface you\u2019re working on quickly.<\/p>\n\n\n\n

The sanding wheel also doesn\u2019t dwell too long on a specific portion of the surface you\u2019re working on, which helps prevent over-polishing or sanding of the area.\u00a0This helps to deliver a better finish overall.<\/strong><\/p>\n\n\n\n

The composition of the tool allows one-click switching from sanding to buffing a surface.<\/p>\n\n\n\n
